JNITED STATES WILLIS L. HALL, OF SAN FRANCISCO, CALIFORLI GALLEY LOCK.

Application filed April 17, 1926, Serial No. 162,819. Renewed September 10, 1928.

This invention relates to improvements in galley locks for locking type in a supportin galley. One object is to provide a galley lOcK that can be manipulated with the use of one hand thus leaving the operatorsother hand free. A further object is to provide a galley lock that is of simple construction and positive and eflicient in operation.

Tt ith the foregoingand other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully describet, pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of this application and in which if 1 is a view of a galley with the type locked in position therein by the lock.

Fig. 2 is an enlarged longitudinal sectional view of the lock.

Fig. 3 is an end view of Fig. 2.

Like reference characters denote corresponding parts throughout the several views.

The reference numeral 1 denotes the galley provided with the type 2 to be secured in position by means of the improved lock. The lock comprises a base block 3 of oblong formation and formed interiorly with the channel i in one end of which the plug 5 disposed, said channel being narrowed at one end to form the passageway 6 for the plunger rod 7 which extends therethrough and into the said channel 4 and is there provided with the integral head 8, said rod 7 passing through a perforation in the cap plate 9 that is fitted toone end of the block 3 and retained in position by means of the screws 10.

Encircling the said rod 7 and abutting the cap plate 9 is the expansion coil spring 12, one end of said spring also riding against the flange 13 of the spool 14 which is secured to one end of the rod 7, the opposite flange 15 of said spool being formed with the face corrugations l6.

The lock is manipulated with the thumb which isapplied tothe end of the block 3 and two fingers applied to the flange 18, the thumb and fingers then being moved toward each other to cause the rod to telescope into the block 8, thus compressing the spring 12. The lock is now placed in the galley as shown in Fig. 1 continguous to one end of the type 2 and when the lock is manually released the spring will expand and cause the lock to frictionally engage with the sides of the galley thus securing the type in position. All parts of the lock are of smaller transverse diameter than the height or" the type, but higher than the sides of the galley.

What is claimed is 1- 1. In a galley lock, an oblong base block formed with a channel and with a communieating passageway of smaller diameter than said channel, the transverse diameter of said base block being greater than the height of a galley side wall above the galley base but less than the height of the type, a plunger rod extending through said passageway into said channel, a head for said plunger rod disposed in the said channel and of a diameter greater than that of said passageway, a spool secured to the outer end of said plunger rod, and an expansion coil spring encircling said plunger rod and yieldingly retaining the same in full extended position relative to said base block, said spool and base block then bearing against opposite sides of the galley and said base block being adapted for positive supporting engagement with the type at one end thereof.

2. In a galley lock, a hollow base block, a plunger rod opcratively supported by said base block and extending into the hollow portion thereof, a head for the inner end of said plunger rod whereby withdrawal of the same from said base block is prevented in one direction, a spool secured to the outer end of said plunger rod. and an expansion coil spring encircling said plunger rod and yieldingly retaining the same in full extended position relative to said base block, said spool and base block then bearing against opposite sides of the galley and said base block being adapted for positive supporting engv einent with the type at one end thereof. T testimony that I claim the foregoing as iy own I have hereto aflixed my signature.
